Dysfibrinogenemia (fibrinogen Dusard) associated with impaired fibrin-enhanced plasminogen activation

The fibrin-mediated enhancement of the activation of plasminogen by tissue-type plasminogen activator observed with normal fibrin, is strongly decreased with fibrin Dusard, although the binding of tissue-type plasminogen activator to this fibrin is normal. This impaired fibrin-mediated plasminogen activation is most likely related to the history of recurrent thrombosis and pulmonary embolism observed in this family.
